Equipment for polishing outer ring of outer spherical cage of automobile

Abstract

The invention relates to the field of outer spherical cages of automobiles, in particular to equipment for polishing an outer ring of an outer spherical cage of an automobile. The equipment comprisesa worktable and further comprises a driving polishing mechanism, a translation mechanism and a rotary tool mechanism mounted on the worktable. The driving polishing mechanism comprises a chuck capableof clamping the outer spherical cage and a driving assembly. The bottom of the driving assembly is fixedly mounted on a table board of the worktable, the chuck is horizontally arranged above the driving assembly, and one end of the chuck is rotatably connected to a working end of the driving assembly. The rotary tool assembly comprises a turning tool and a rotary driving assembly. An output end of the turning tool and the axis of the chuck are in a same horizontal plane., the bottom of the rotary driving assembly is movably arranged on the worktable, the turning tool is located above the rotary driving assembly, the turning tool is fixedly arranged at the working end of the rotary driving assembly, and the translation mechanism is located on one side of the rotary driving assembly and comprises a movable plate capable of translating the rotary driving assembly in a direction of the chuck. The equipment is easy to operate and can machine the outer ring precisely.

Description

Technical field [0001] The invention relates to the field of automobile outer ball cages, in particular to a polishing equipment for the outer ring of automobile outer ball cages. Background technique [0002] Many cars are now driven by front wheels. The gearbox and drive axle of this model are integrated. The wheels and the gearbox are connected through two half shafts to drive the vehicle. Because the relative position between the wheels and the gearbox often changes, The angle between the power output end and the input end often changes, so it needs a universal transmission device to adjust. This universal transmission device is what we often call the ball cage. There are two types of ball cages commonly used on cars. One is a fixed ball. Cage universal joint RF joint, its characteristic is that in the process of transmitting torque, the driving shaft and the driven shaft can only rotate relative to each other without axial displacement. It is usually used near the wheel, whi...

Problems solved by technology

[0002] Nowadays, many cars are front-wheel drive. The gearbox and drive axle of this model are integrated, and the wheels and gearbox are connected through two half shafts to drive the vehicle. Since the relative position between the wheels and the gearbox often changes, The angle between the power output end and the input end changes frequently, so it needs a universal transmission device to adjust. This universal transmission device is what we often call a ball cage. There are two types of ball cages commonly used in cars, one is a fixed ball cage Cage universal joint RF joint, its characteristic is that in the process of transmitting torque, the driving and driven shafts can only rotate relative to each other without axial displacement. It is usually used near the wheel, which is what we often say The outer ball cage, the other is the telescopic ball cage universal joint VL joint, which is characterized in that in the process of torque transmission, the driving and driven shafts can not only rotate relative to each other, but also can produce axial displacement, It is usually used near the drive axle, which is what we often call the inner ball cage. These ball cages on the car are subjected to medium and alternating loads during use, so they will be damaged after a long time, and even make the car Unable to drive. Generally, the most obvious feature of damage to the outer ball cage is that the car is normal when driving in a straight line, but there is a rattling sound on the front wheel when turning. In severe cases, it is impossible to turn. The most obvious feature of damage to the inner ball cage is that the car When accelerating or when the car is driving on an uneven road, there will be a rattling sound at the gearbox, accompanied by oil leakage from the ball cage. The ball cage requires very high precision, especially for the processing of the outer ring of the car outer ball cage. The outer ring of the car outer ball cage is similar to a circular body structure, and it is difficult to precisely process the outer ring surface of the car outer ball cage during processing , therefore, we propose a polishing equipment for the outer ring of the outer ball cage of the automobile, in order to solve the above-mentioned problems
